There are 12,000 Btus per ton of cooling.
In order to determine tons of cooling, the formula is:
Tons = (dT x GPM) / 24
If you would like to know the tons of cooling in Btus, you would multiply this formula by 12,000..
Tons (Btu) = (dT x GPM x 12,000) / 24
Basic arithmetic yields:
Tons (Btu) = (dT x GPM x 500)
{12,000 / 24 = 500}

How many BTU per Hour equals 1 kilowatt?
1kW is 3,412.13 BTU/hr
10000 btu equals how many pounds ao propane an hour?
A 10,000 BTU heater will use about 1/2 pound of propane per hour. Conversions to different types of energy being used (ie steam, KwH, etc.) will vary the answer, as will variations such as leaks, 02, temperature setting, efficiency, etc.
One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
How many btu's would it take to raise the temperature 1 degree?
This question can not be answered without know much more information. Such as the material that needs to have its temperature changed. How much of that material there is.
How many btus to raise 1 pound of water from room temp deg to steam 213 deg?
First convert 1 lb of water to lb-moles which is 0.055 lb-moles (you'll need this later). This problem can be broken into 3 steps:(1) You need to detemine how much heat is needed to raise room temperature water (68oF) to 212oF. This can be used using the heat capacity of water which at room temperature is 1 Btu/lboF. So the amount of heat needed for this is:Q1 = m*Cp*ΔT= (1 lb)*(1 Btu/lboF)*(212 - 68oF)= 144 Btu(2) Next you need to account for the phase change. The water changes to steam at 212oF. You use the heat of vaporization which you can look up in any Chemistry or Chemical Engineering Handbook. The Hvap that I found is 17493.5 Btu/lb-mole.Q2 = n(lb-moles)*Hvap= (0.055 lb-moles)*(17493.5 Btu/lb-mole)= 972.64 Btu(3) Next you need to find out how much heat is needed to raise the temperature of the steam from 212 to 213oF. You can look up the heat capacity of steam at 212oF to be 0.485 Btu/lboF.Q3 = m*Cp*ΔT= (1 lb)*(0.485 Btu/lboF)*(213-212oF)= 0.485 BtuTo find the total heat needed add Q1+Q2+Q3 (144+972.64+0.485) =1117.12 Btu
How many BTU's required to raise 500 cubic feet 250 degrees?
7,803,495 BTU's Assuming it's water that's being heated and the temperature is Fahrenheit: 500*250*62.42796 (<the weight of one cubic foot of water)= 7,803,495 BTU's
Converting therms to btu?
To convert therms to BTU, you can use the conversion factor: 1 therm = 100,000 BTU. Simply multiply the number of therms by 100,000 to get the equivalent number of BTU.
How many btu to heat 512 gal of water to 180 degree in 2hr?
-- That's going to depend on the total temperature rise, i.e. the difference between 180 and the starting temperature, which isn't given. -- Knowing the starting temperature, the energy (BTU) required to do the job depends only on the amount of water and the temperature rise. The length of time isn't involved.
How hot is 400000 BTU?
BTU is not a measure of temperature.
How many Kilowatts equals 15000 BTU?
Btu x 0.000293 = kW 15000 X 0.000293 = 4.4kW
Calculating Btu's to therms?
1 therm unit equals 100000 btu's
What is the temperature rise of 250 cfm of air if an electric heater adds 8500 btus to the air?
Assuming no heat loss, the temperature rise would be approximately 36 degrees Fahrenheit. This calculation is based on the specific heat capacity of air, which is about 0.24 BTU/lb°F. The formula for calculating temperature rise is: Temp Rise = Q / (m * Cp), where Q is the energy added in BTUs, m is the mass flow rate of air in lbs per minute, and Cp is the specific heat capacity of air in BTU/lb°F.
Does temperature decrease of gasoline increase BTU value?
No, the BTU (British Thermal Unit) value of gasoline does not increase if the temperature decreases. The BTU value of gasoline is a measure of its energy content and is not affected by temperature changes.
What size btu do you need for a 500 sq ft room portable type?
At least 8000 btu
How do you compute BTU of a heater using CFM and output temperature?
To calculate the BTU of a heater, you can use the formula: BTU = CFM x (Temperature rise in °F) x 1.08. Convert CFM to cubic feet per hour, measure the temperature difference between the air entering and exiting the heater, and multiply by 1.08, which is a constant factor. This will give you the BTU output of the heater.
What does a ton equals?
12000 btu/min
How many BTU per Hour equals 1 kilowatt?
1kW is 3,412.13 BTU/hr
